Associations Between Diet, Oral Health, and General Development in Romanian School-Age Children.

BACKGROUND

The prevalence of dental caries has increased among children, largely due to nutritional habits or inadequate access to dental care. The present study aimed to investigate the prevalence of dental caries associated with various factors that lead to their appearance, such as food intake and body composition, among Romanian school-age children from two counties, Bistriţa Năsăud and Mureş.

METHODS

This cross-sectional study included 1100 children aged 6-10 years from two Romanian counties. Dental caries experience was assessed using the DMFT and dmft indices based on WHO criteria. Dietary intake and oral health behaviors were evaluated through a food frequency questionnaire completed by parents. Associations between dietary variables and dental caries were assessed using independent sample -tests and Mann-Whitney U tests. A binary logistic regression model was used to estimate the likelihood of caries in the permanent dentition (DMFT > 0), with covariates including county, parental education, daily sugar intake, consumption of dairy products, body mass index (BMI), and waist-to-height ratio.

RESULTS

It was found that the children who daily consume cheese recorded a DMFT value lower than the children who did not consume ( < 0.05). Moreover, those who consume sugary foods recorded higher values of DMFT as compared with those who did not ( < 0.05). The body weight, BMI, and waist circumference are positively correlated with DMFT, but negatively with dmft ( < 0.05). The overall prevalence of caries was 79.8% in primary dentition and 63.6% in permanent dentition, with slightly higher rates observed in Bistriţa-Năsăud County compared to Mureş. It seems that the predictors of the caries's presence among children include the mother's education level, sugar intake frequency, and body fat ratio.

CONCLUSIONS

Based on significant associations found, one can affirm that the dental caries of the Romanian school-age children is due to sugary food intake and body composition. In addition, the direct relationship between dental caries and childhood obesity showed through the correlation of BMI and dental health indices denotes that school-age children should reduce sugary foods and increase dairy products.
